Abstract (en)
[origin: EP1524892A2] The circuit has electronic components (4) which produce operating heat during operation, and a circuit board (1) on which the electronic components are mounted. A heat sink (6`) dissipates the operating heat from the electronic components. The electronic components rest flat on a contact surface of the heat sink, where the contact surface includes an angle of 10-70 degrees with the circuit board. An independent claim is also included for a method for mounting an electronic component.
